IS THERE ALIEN LIFE?
• Performed: Pisarchuk Vera, Koposova Maria, Linker
Milana, Mataitis Victoria.

2.

• For thousands of years, people on Earth believed our planet was
special because they thought it was the only planet with life.

3.

Exoplanets
In 1992, astronomers discovered the first exoplanets. These are planets
that orbit a star outside of our solar system.

4.

Kepler-186f
• Kepler-186f was the first
Earthsized exoplanet
found in the habitable
zone of a star.

5.

Kepler-438b
Initial investigations have shown
that this exoplanet is the most
similar to Earth yet discovered.
It’s very similar in size, only
about 12% bigger than our
planet. Scientists can’t be sure
yet, but the temperature on the
surface could be between O and
6O°C (32–14O°F). One big
difference to Earth would be the
length of a year – just 35 days on
Kepler-438b

6.

Space Invaders
• Astronomers have recently discovered signs of complex organic
molecules out in space in giant dust clouds.

7.

Sutter’s Mill Meteorite
• In April 2O12, a meteorite struck California, USA, near Sutter’s Mill.

1. There are some planets, they're outside the solar
system,
3. Scientists are finding out how life appeared,
Someone said that our world's made of chemical
Their life is a rotation around the star,
blocks.
I guess, you'd know about their existence
Maybe comets and asteroids helped us to be
Please tell me, how were these planets named by
there,
scientists?
And you know about the theory in this little
verse.
2. Frank Drake created a special formula
4. There are many galaxies in the universe,
To know that we're not alone in the space...
But we only live in one of them...
He said: 60 billion planets are similar
Our galaxy seems really enormous,
But what is it called? Can you please say?
To our one... So the name of formula is...
